摘要： A capacitor packaging having a central termination and three or more capacitors (or groups of capacitors) arranged about the central termination. The electrical flow paths between the termination and the capacitors or groups of capacitors are of substantially the same length. The capacitors or groups of capacitors may be arranged in a generally circular pattern with the termination centered on the center. The termination may include first and second terminals. The capacitors may be mounted to a printed circuit board (“PCB”) with traces on opposite surfaces of the PCB providing electrical flow paths from the terminals to opposite legs of the capacitors. The capacitor packaging may include a primary PCB with a first circular arrangement of capacitors and a secondary PCB with a second circular arrangement of capacitors. The capacitors may be sandwiched between the PCBs with the second arrangement of capacitors disposed concentrically inwardly of the first arrangement.

摘要： The invention comprises a method for manufacturing an inductor, comprising the steps of: casting a cast winding comprising an inner cavity; inserting a first inductor core subsection into the inner cavity; inserting a second inductor core subsection into the inner cavity; and mechanically coupling the first inductor core subsection to the second inductor core subsection to form an inductor core wound by the cast windings. The method of manufacturing optionally includes the steps of: forming at least a portion of the cast winding into an arced helical shape; forming the first inductor core subsection and the second inductor core subsection into elements of a torpid shaped inductor core; deforming the cast winding to physically allow the step of inserting the first inductor core subsection into the inner cavity; and/or deforming at least a portion of the cast winding into an arced helical coil shape after the step of inserting.

摘要： An apparatus includes a case having an elliptical cross-section capable of receiving a plurality of capacitive elements. One or more of the capacitive elements provide at least one capacitor having a first capacitor terminal and a second capacitor terminal. The apparatus also includes a cover assembly that includes a deformable cover mountable to the case, and, a common cover terminal having a contact extending from the cover. The cover assembly also includes at least three capacitor cover terminals, each of the at least three capacitor cover terminals having at least one contact extending from the deformable cover. The deformable cover is configured to displace at least one of the at least three capacitor cover terminals upon an operative failure of at least one of the plurality of the capacitive elements. The cover assembly also includes at least four insulation structures. One of the four insulation structures is associated with one of the at least three capacitor cover terminals. The apparatus also includes a first conductor capable of electrically connecting the first capacitor terminal of a capacitor provided by one of the plurality of capacitive elements to one of the at least three capacitor cover terminals and a second conductor capable of electrically connecting the second capacitor terminal of the capacitor provided by one of the plurality of capacitive elements to the common cover terminal.

摘要： The invention relates to a film capacitor for power electronics, which comprises a first electrically conductive layer, which is arranged on a first end side face of the film capacitor, wherein the surface normal of the first electrically conductive layer is perpendicular to the surface normals of dielectric films of the film capacitor. A second electrically conductive layer is arranged on a second end side face opposite from the first end side face, wherein the surface normal of the second electrically conductive layer is perpendicular to the surface normals of the dielectric films of the film capacitor. The film capacitor has at least one inner passage, which extends from the first electrically conductive layer to the second electrically conductive layer, wherein the passage is formed by removal of capacitor material. The invention also relates to a capacitor assembly.
